CLIP OR HOLDER FOR CLOTH-STRETCHING MACHINES.

SPECIFICATION forming part of Letters Patent No. 404,314, dated May 28,1889.

Application filed August 23, 1888. Serial No. 283,548. (No model.)Patented in England February 25, 1887, No. 2,912, and in France February23, 1888, No. 188,920-

To all whom it may concern:

Be it known that 1, DAVID PIOKEN SMITH, a subject of the Queen of GreatBritain, residing at Salford Iron WVorks, near Manchester, in the countyof Lancaster, England, have invented new and useful Improvements inClips or Holders for Cloth-Stretching Machines, (for which I haveobtained a patent in Great Britain, dated February 25, 1887, No. 2,942,and France, dated February 23, 1888, No.188,920,) of which thefollowingis a specification.

This invent-ion relates to clips or holders employed in machines forstretching or finishing woven fabrics, in which these are operated uponand carried by endless chains or equivalent means fitted with clips forholding the fabric by its selvages, so that as the chains are made todiverge from each other the clips effect the stretching of the fabric.

According to the present invention such clips or holders are constructedwith a fixed horizontal lower jawand an upper movable jaw, which iscaused by gravity to drop onto the lower jaw, so as to grip the selvageof the fabric between them, but which is prevented from so gripping thefabric until the selvage is in the exact required position betweenthejaws by means of a regulating-guard connected to the movable jaw, and soarranged as to bear upon the selvage of the fabric, and thereby keep themovable jaw in a raised position until the selvage has been brought tothe exact required position between the jaws, when the regulating-guard,losing its support, will drop into an opening in the lower j aw, andwill thus all ow the movable upper j aw to come in contact with and gripthe fabric. The movable upper jaw and its adjustable regulating-arm canbe constructed in a variety of ways for fulfilling the above describedfunctions.

Figure 1 of the accompanying drawings shows a sectional view of the clipor holder connected to a link of the endless chain,with one form ofmovable jaw and regulatingguard, the fabric being in such a position inthe clip that the guard holds the upper jaw in and a back view ofanother modification.

Figs. 10 and 11 show, respectively, a crossseotional and a back view ofanother modification. Figs. 12 and 13 show, respectively, across-sectional and a back view of another modification. Figs. 14 and 15show, respectively, a cross-sectional and a plan View of anothermodification; and Fig. 16 is a sectional view, on a reduced scale, takenon the lines so :10, Fig. 15.

The clip or holder consists of a lower jaw, A, formed in one with thelink B of the endless chain and having two arms, D, to which is pivotedat E the upper jaw, F. This is made to slant inward to a slight angle,so that when it rests upon the fabric, X, with its lower chisel-edge andan outward pull is put upon the fabric it will nip the fabric firmlyupon the slotted plate 0 of the lower jaw. The regulating-guard Gconsists of a bent piece of wire, which is adapted to slide verticallyin a socket, H, which in turn is adapted to slide horizontally in anorifice in the upper end of the jaw F, for the purpose of adjusting thelower end of the guard in a vertical and a horizontal directionrelatively to the grippingedge of the jaw F. The guard G is held in theposition to which it is adjusted vertically by a set-screw, H, tappedinto a socket, H, to bear against that part of the guard which is withinthe socket, while the latter is held in the position to which it isadjusted horizontally by a set-screw, H tapped into the jaw F to bear ona shank or stem, H forming a rigid part of the socket.

WVhen the fabric, X, is inserted between the jaws in the position shownin Fig. 1, the end of the guard resting on the fabric will keep theupper jaw raised, so as not to grip the fabric; but when the lattermoves outward to such an extent as to deprive the guard of its supportit will fall into the slot 0 of the plate 0 on lower jaw, and thus allowthe upper jaw to grip the fabric, as shown in Fig. 2. It will be seenthat the exact position of the selvage when this grip is effected willdepend upon the exact adjustment of the regulating-guard relatively tothe upper jaw, and consequently this capability of adj ust-mentto suitdifferent kinds of fabrics to be treated is of great importance.

I is a weight adjustable on the stem of the socket II, for balancingto acertain extent the weight of the socket II and guard G, so as toregulate the pressure with which this bears on the fabric.

Fig. 5 shows a back view, Fig. 6 a seetional view, and Fig. 7 a plan, ofan arrangement in which the regulating-guard consists of a forked stem,G, vertically and horizontally adjustable in the slot of a lug, F, onthe upper jaw, F, and carrying a roller, G, which rests upon the fabric,so as to raise the jaw F until the fabric is drawn outward to therequired extent.

The means for adjusting the guard (shown in Figs. 5, (3, and 7) comprisethe slot F in the lug F and nuts F F, respectively, engaging thescrew-threaded part of the fork ed stem above and below the lug, so thatby loosening one nut the forked stem can be moved along the slot andthen be fixed in its adjusted position by tightening such nut, while byturning the two nuts in the proper direction the forked stem can beraised or lowered in the slot.

In the arrangement shown in Figs. 8 and 9 the upper jaw, F, has ahorizontally-slotted arm, F, to which is secured, by means of apinching-screw, K, the vertically-slotted arm G of the regulating-guardG, which is thus adjustable in all directions.

In Figs. 10 and 1.1 the jaw F, carried by the pivot E, is provided witha transverse orifice, into which screws the threaded shank of the guardG, so that by axially rotating the guard in the proper direction itslower or free end is adjusted horizontally toward or from thegripping-edge of the jaw F. The guard in this construction is composedof a piece of wire, which can be bent up and down to secure the requiredvertical adjustment of its lower end relatively to the plate C and jawsA and F.

In Figs. 12 and 13 the jaw F, carried by the pivot E, furnished with alug, F, having a socket, II, in which is arranged the guard G.

The guard is composed of a piece of wire screw-threaded at its upper endand screwing into the socket, so that by axially turning the guard inthe proper direction it is raised or lowered. The socket II is providedwith a screw-threaded shank, II", engaging a screwthreaded orifice inthe lug F, to secure the horizontal adjustment of the guard relativelyto the plate O and jaws A and F.

I do not confine myself to an adjustable guard capable of varying theposition of its lower end relatively to the fixed and movable jaws. Imay form the guard G rigid with the movable jaw F, as in Figs. 14, 1.5,and 16, where the letter I3 indicates a link formed with the two upperarms, D, to which the jaw F is pivoted by a pivot, E, and with a lowerjaw, A, to coact with the pivoted jaw and plate (3. The link B has atenon, 13, at one end engaging a recess in a bar, 13 and secured by apin, B, to connect the link 13 with another link (not shown) constructedthe same as the said link 13. In the example shown in liigs. ll, 15, and.16 the clip or holder comprises two guards, G, formed integral. withthe jaw F and located, respectively, at the end portions thereof. Theoperation of the guards is the same as described with reference to theother constructions, except that such guards are not adjustablerelatively to the movable jaw.

Having thus described my invention, what I claim is 1. The combination,with a link, of a clip or holder composed of a lower jaw fixed on thelink, a pivoted upper jaw that drops by gravity toward the lower jaw togrip the fabric between them, and a guard carried by the pi voted jaw torest on the fabric and keep the upper jaw raised until the fabric isdrawn under the guard, substantially as described.

2. The combination, with a link carrying a fixed lower jaw, of a pivotedupper jaw that drops by gravity toward the lower jaw to grip the fabricbetween them, a guard movably connected with the pivoted jaw to rest onthe fabric and keep the upper jaw raised until the fabric is drawn fromunder the guard, and means for adjusting the lower end of the guard toand from the gripping-edge of the pivoted jaw, substantially asdescribed.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 8th day of August, A. I).1888.
